Abstract
A tibial prosthesis locking system. The system includes a tibial plate and an articular surface component or tibial insert. A proximal side of the tibial plate includes perimeter sidewalls with holding flanges formed thereon, and male retaining projections are formed on interior portions of the proximal tibial plate. A distal side of the articular surface component is designed to interlock with the holding flanges and retaining projections formed on the tibial plate. The male retaining projections and the holding flanges cooperatively engage with the articular surface component to provide it with resistance to movement in an anterior-posterior direction, a medial lateral direction, a rotational direction, and a vertical direction.
